Of the 1,200 single spore isolates of Alternaria mali causing apple leaf spot and fruit decay, the mycelial colonies showed 76, 96 and 15% growth at 100,000 micro g/ml of captafol, chlorothalonil and folpet, respectively, and five and three percent growth at 10,000 micro g/ml of iprodione and polyoxin. These isolates showed cross-tolerance of mycelial growth, spore formation, or spore germination to the above five fungicides plus captan, garbenda, and thiophanate methyl. Captafol, mancozeb, polydong, and propineb did not show any cross-tolerance of spore germination since no spore was germinated at 10 micro g/ml which was much lower than the concentration used by apple growers
